Answer:
C. Direct Variation; y = 5x
Step-by-step explanation:
As we can see on the table, when x is 1, y is 5. When x is 3, y is 15. When x is 4, y is 20. When x is 7, y is 35. In all of these instances, y is 5 times greater than x (1x5 is 5, 3x5 is 15, 4x5 is 20, and 7x5 is 35). That means y is equal to 5 times the quantity of x, or, y = 5x.
